The products being recalled were made between April and June 2008 and include nearly two dozen varieties, such as Children's Tylenol Suspension 4 oz. Grape, Infants' Tylenol Grape Suspension Drops 1/4 oz. and Children's Tylenol Plus Cold & Allergy 4 oz. Bubble Gum.

Johnson & Johnson said late Thursday it has contacted wholesalers and retailers about the recall. An inactive ingredient didn't meet internal testing requirements, the company said, and B. cepacia bacteria were detected in a portion of raw material that went unused in the finished product.

The company said in a letter that no bacteria were found in the finished product, and that the likelihood of a serious medical event is remote. But it said it decided after consulting with the Food and Drug Administration that it would recall the products.

"It was decided, as a precaution, to recall all product that utilized any of the raw material manufactured at the same time as the raw material that tested positive for the bacteria," the company said.
